How much GPU energy does fp16 save? Measured on a Tesla T4
How much GPU energy does fp16 actually save over fp32? Spec sheets give TDP and peak FLOPS, not joules per job, so I measured it on a Tesla T4 using the GPU's own NVML energy counter. The job import sys , torch dtype = { " fp16 " : torch . float16 , " fp32 " : torch . float32 }[ sys . argv [ 1 ]] a…
